e The plates are each provided with'a collar 20 to receive the conduit 10, and these collars 20 are each of a length greater than the length of the flanges 16 and are slightly tapered, as will be clearly seen in Fig. 3, so that the edge of one collar extends into the cylindrical opening of the collar of the next plate as shown in Fig. 3 by which arrangement the collars are wedged toward the conduit and are forced into tight and secure engagement with the conduit 10 to form a good contact for the transfer of heat from the heat conducting conduit 10 to the radiating fins or plates where it may be picked up by the circulation of air. I

I have illustrated in Fig. 4 an additional deflected portion 21 which may occur at such intervals as desired along the plate 13 to increase the radiating surface thereof.

This invention is shown as primarily adapted for a one pipe system whichmay be inclined to prevent the forming of traps or although circuitous travel of the 10 where desired.

The foregoing description is directed sole- 1 towards the construction illustrated, but

desire it to be understood that I reserve the privilege of resorting to all the mechanical device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. In a heat transfer apparatus, a tubular conduit, a plurality of plates disposed in parallel planes extending transversely of and around said conduit and means for spacing said plates along a portion of their edges, saidmeans being integral with said plates and so constructed and arranged as to prevent both around said conduit and a tapered collar having an unbroken surface on each plate of a width greater than the distance between said plates and tightly embracing said conduit, substantially throughout the length of the collar, said collars telescoping one within the other.

5. In a heat transfer apparatus, a tubular conduit, a plurality of plates disposed in parallel planes extending transversely of and around said conduit, flanges on said plates, and a collar on each plate tightly embracing said conduit, said collars telescoping one within the other and means to prevent telescoping and collapsing of said flanges.

6. In a heat transfer apparatus, a tubular conduit, a plurality of plates disposed in parallel planes extending transversely of and around said conduit, and a collar on each plate tightlyembracing said conduit, said collars telescoping one within the other, the edges of said plates being bent to provide laterally extending flanges with inturned lips to prevent telescoping of the flanges one on the other, and means to prevent collapsing of said flanges.

7. In a heat transfer apparatus, a tubular conduit, a plurality of metal plates disposed in parallel planes extending transversely of and around said conduit, and a collar on each plate tightly embracing-said conduit, said collars telescoping one within the other, the edges of said plates being bent to provide laterally extending flanges with inturned lips to prevent telescoping of the flanges one on the other, and laterally extending abutments positioned inwardly from the edges of said plates with which said lips engage to prevent collapsing of said flanges.

In testimony whereof I aflix my signature.

3.
